Smart meters cause massive headaches, major depression, back pain, etc...but I found the solution. I wrapped mine in aluminum foil, shiny side inward...problem solved. Symptoms all went away. I bought a cheap emf detector off Amazon, took before and after readings, and this confirmed that it works. The foil blocks all deadly emfs coming from the meter. My 23 year old son thought of this...the kid has a mind of a scientist, and brilliant. Homeschooling paid off.

As someone with a background in radio, it shouldn't matter if the shiny side is in or out. Just a metal cage around an RF source would block the signal. Unfortunately for you, the signal will still emanate from the power lines.
